To aZleo/zom it may concern. a

Be it known that I, Jossrn A. House, of Stamford, in the countyof Fairfield and State of Connecticut, have invented certain new and useful Improvements in Coin-Controlled Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it up ertains to make and use the same.

11y invention relates to an improvement in coin controlled locks, the object of the invention being to provide a coin controlled lock for lockers and other receptacles in public places, the construction being such that a person, b insertin the )rolper com can purchase tto use the occcr, and when he returns with the proper key, can open the locker and regain llS pro crty stored therein, whereupon the key will be tra )ped in the lock and cannot be turned for locking the door, or be removed until another coin is inserted and the operation repeated.

With this object in view my invention consists in a trapping lever connected to the bolt and resting in the nth of movement of the coin, whereby the weight of the coin moves the trap ing lever to a position to release the bolt tius permitting the key to be turned to a position to reject the bolt and to be withdrawn from tiie lock.

My invention further consists in the parts and combination of parts and in the details of construction as will be more fully explained and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in elevation of the lock showing the bolt retracted. Fi 2 is a similar view with the bolt projecte d, and Figs. 3 and 4 are similar views with the face plate of the lock removed.

1 represents a lock; 2 the bolt, the shank receptacle. By again inserting the key and of which 18 slotted as shown; 3 the key plu taming; it to the right, the bolt will be remounted at its ends in the lock case, an tracte and it and the key will both be 1mprovided with a groove for the reception and passage of the key 4, and 5 are the tumblers pivotally mounted on the post (3 and adapted to engage the fence 7 on the bolt and hold the latter in its projected position. By turnin the key, the tumblers will be moved unti the gates therein aline with the I Specification of I ietterl Patent. 1 Application filed July 17,1909." Serial No. 508,240.

' Patented Mar. 4,1913.

The arts above referred to may be of any will "known and approved forms of locks now in common use. p

8 is the trapping lever pivotally secured to the rear end of the bolt, and projecting outwardly through the slot 9 in the rear end of the lock case. This lever 8 is provided with a shoulder 10, which, when the bolt is retracted, rejects outside of the lock case, and is held up a ainst the wall of the slot in the lock case y the spring 11, carried by the shank of the bolt and engaging the lever. The rear end of this lever, when the bolt is retracted, rests within, or adjacent to a coin chute l2, and in the path of movement of the coin passing through said chute, so that the weight of the coin comes in contact with the upper edge of the trapping lever 8, and by depressing same frees the shoulder 10 from its engagement with the lock case, thus freeing the bolt, and permitting it to be projected by its key.

he escutcheon 13 is provided with a lip 14, having a slot 15 which alines with the groove in the key plug, when the bolt is projected. The key is slotted as at 16 for the.entrance of the lip 14, hence it will be seen that the key cannot be removed from the lock, except when the bolt is in its projected position. When the bolt is retracted the key will be tra oped, and so held until the bolt has been re eased by the deposit of a )roper coin into the coin chute.

he weight of the coin, resting on the trap iing lever disenga es the shoulder on the ever from the loot case, thus freeing the bolt and permittin it to be projected bv its key. 1 After the be t has been n'ojecte'd, the key may then he removed. he projection of the bolt carries the trapping lever from under the coin, thus releasing the latter and permitting it to fall into the coin trap ed by the engagement of the lever with the ock casing, until again released by the proper coin.

The coin chute 12 is shown in the present instance as attached to the lock casing. It may however be attached to any convenient part of the locker or other receptacle to til) to be retracted by the continued movement fence onthe bolt, thus permitting thelatter which the lock may be applied, but must, of

course, be so located with relation to the trapping lever, that, when thev bolt is reof the key.

tracted, the outer free end of the lever will obstruct the chute and prevent the passagev of a coin throughithe same. The com rests on the trappin lever until the bolt is moved to its projecte position b the key. As the bolt moves forwardly, tie trapping lever will be moved in the same direction and out of the passage in the coin chute, thus permittin the coin to drop 'into the coin receptac e.

As the weight of the coin is removed from the lever, the spring moves the latter to its normal position, so that when the bolt is again-retracted, the tra ping lever will engage the lock case an absolutel revent a second projection of the bolt until t e lever has been again released by a coin falling and resting thereon.

It is evident that many slight changes might be resorted to in the relative arrangement of parts shown and described without departing from the spirit and scope of my invention hence I would have it understood that I do not wish to confine myself to the exact construction and arrangementof parts shown and described, but,

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is

1. In a coin controlled lock, the combination with a bolt and a key for actuating same, the escutcheon and key having engaging parts whereby the key can be inserted in, or removed from the lock, only when the bolt is in its projected position, of a ivoted trapping lever movable longitudinal y with the bolt and adapted when the bolt is retracted, to engage a stop and lock the bolt in its retracted position, and a coin chute which is obstructed by the trapping lever when the an bolt is retracted.

2. In a coin controlled lock, the combination with a bolt, a key for actuating same, the escutcheon and key having engaging parts whereby the key can be inserted in, or removed from the look, only when the bolt is in its projected position, and a coin chute of a trapping lever pivoted to the bolt an adapted when the bolt is retracted, to engage a stop and lock the bolt in its retracted position and also obstruct the passage through the coin chute whereby the weight of a coin deposited in the chute disengages the lever from its stop and permits the bolt to be projected by the key.

3. In a coin controlled lock, the combination with a bolt, a ke for actuatin same, and means for preventing the removaI of the key from the lock except when the bolt is projected, of a coin chute, a t-ra ping lever pivote'd to the bolt and provi ed with a shoulder adapted to enga e a stop when the bolt is retracted and 100: the bolt against the action of the key, the said trapping lever resting in the path of a coin in the coin chute when the bolt is retracted, and a spring normally tending to hold the shoulder on the lever in contact with the stop.

In testimony whereof, I have signed this specification in the presence of two subscrib- 7 ing witnesses.
